Abstract
The utility model relates to a quickly adjustable prestressed anchoring device, which is used for fast and conveniently anchoring various anchoring bolts in various supporting and protecting of side slopes and in foundation engineerings. The structure of the utility model is composed of a supporting plate, a regulating nut, a sleeve cylinder of the anchoring device, and a locking pin. The supporting plate is a supporting body of the prestressed regulating nut, screw threads are arranged in the regulating nut which is connected with the sleeve cylinder of the anchoring device, the inside of the sleeve cylinder is a cone surface which is contacted with the locking pin, and the outside of the sleeve cylinder of the anchoring device is connected with the regulating nut through the screw threads. The inside of the locking pin is a cylindrical surface, the outside of the locking pin is a conical surface, and the locking pin is divided into four parts along the orthogonal direction. The outline of the regulating nut is a round ring surface, and the regulating nut is divided into four planes along the orthogonal direction.
Description
What the utility model quick adjustable prestressed anchor related to is a kind of ground tackle that is applicable to the various anchor poles of anchoring quickly and easily in various slope retainings and the Foundation Design.
The ground tackle of present traditional handicraft is finished screw rod in the rock bolt head welding generally, loads prestressing force by its upper cap nut lock anchor club head screw thread.Operation is loaded down with trivial details in work progress, poor reliability, and the rock bolt head screw thread is if any damage, can can't scrap by loading stress because of anchor pole, causes waste, influences construction quality and duration.
The purpose of this utility model is to exist weak point that a kind of quick adjustable prestressed anchor is provided at present ground tackle, have supporting plate, adjust nut, lock pin, four parts of ground tackle sleeve pipe, can realize the anchor pole quick anchoring by this ground tackle, increase work efficiency, simultaneously can adjust prestressing force again, improve the engineering anchoring quality.
The quick adjustable prestressed anchor takes following scheme to realize: quick adjustable prestressed anchor structure is made of supporting plate, adjustment nut, ground tackle sleeve pipe, lock pin.The supporting plate bottom contacts with stress wallboard upper bearing plate, is again simultaneously the supporting mass that prestressing force is adjusted nut.Adjusting in the nut has screw thread, is connected with the ground tackle sleeve pipe, and adjusting the nut external form is the garden anchor ring, is cut into four planes in orthogonal directions, so that carry out stress compensation by the screwing length of transferring torque wrench to adjust screw thread.In the ground tackle sleeve pipe is the garden conical surface, contacts with lock pin, links to each other by screw thread with the adjustment nut outward.In the lock pin is the garden cylinder, is outward the garden conical surface, is divided into four parts along orthogonal direction again.
Operating principle: at first, ground tackle is inserted in all earlier will loads on the prestressed anchor pole, anchor pole is loaded, the soil body is squeezed, is out of shape, and anchor pole outwards has certain overhang (relevant with loading stress, soil body geology etc.).Ground tackle is pushed into the bottom of anchor pole extending area rapidly and is close to body of wall, lay lock pin, then the slow release stretching force, unloading, anchor pole bounces back under the effect of soil body screen resilience, and lock pin shrinks simultaneously with anchor pole, and make the garden awl on the ground tackle sleeve pipe fit tightly locking with the garden conical surface on the lock pin.Anchor pole is owing to failing to return back to fully original position at this moment, and prestressing force is able to loaded.Owing to the loose feature of the soil body, after the process certain hour, prestressing force discharges to some extent in the anchor pole, at this moment can be by the adjustment nut, and the screwing length of adjustment and ground tackle casing threads, thus the prestressing force in the adjustment anchor pole reloads anchor pole.
The quick adjustable prestressed anchor is reasonable in design, and is simple in structure, need not carry out screw thread processing or welding screw rod to rock bolt head, avoided worrying in the construction operation problems such as the impaired and welding quality of screw thread is not high.Realize the anchor pole quick anchoring by this ground tackle, increase work efficiency, can adjust prestressing force again simultaneously, improve the quality of engineering anchoring, can be widely used in the various anchor poles of anchoring quickly and easily in various slope retainings and the Foundation Design.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is a quick adjustable prestressed anchor structural representation.
Fig. 2 is a quick adjustable prestressed anchor vertical view.
Constitute by supporting plate (1), adjustment nut (2), ground tackle sleeve pipe (4), lock pin (3) with reference to accompanying drawing quick adjustable prestressed anchor structure.Supporting plate (1) is the supporting mass that prestressing force is adjusted nut (2), and adjusting in the nut (2) has screw thread, is connected with ground tackle sleeve pipe (4), adjusts nut (2) external form and is the garden anchor ring and be cut into four planes in orthogonal directions, is used to transfer the torque wrench adjustment.In the tool sleeve pipe (4) is the garden conical surface, contacts with lock pin (3), link to each other by screw thread with the adjustment nut outward, and be the garden cylinder in the lock pin (3), be outward the garden conical surface, and be divided into four parts along mutually perpendicular direction.
Claims (4)
1, a kind of quick adjustable prestressed anchor, it is characterized in that its structure is made of supporting plate, adjustment nut, ground tackle sleeve pipe, lock pin, supporting plate is the supporting mass that prestressing force is adjusted nut, adjust in the nut screw thread is arranged, be connected with the ground tackle sleeve pipe, in the ground tackle sleeve pipe is the garden conical surface, contacts with lock pin, is connected by screw thread with the adjustment nut outward.
2, quick adjustable prestressed anchor according to claim 1, it is characterized in that adjusting the nut external form is the garden anchor ring, is cut into four planes in orthogonal directions.
